National Presto Industries reports a system outage that hit shipping and manufacturing

National Presto Industries, which makes housewares and small appliances as well as defence products, disclosed on March 6, 2025 that a cybersecurity incident on March 1 caused a system outage. Shipping, receiving, some manufacturing processes and back-office work were affected.

What the company reported

The filing listed the operations hit and said many were being restored.

National Presto's language on materiality was tentative. It said forensic work had not produced conclusive evidence about the nature of the incident, and that it had notified law enforcement and would notify regulators and consumer protection agencies as required.

What remains unknown

The filing does not identify which of the company's business segments were affected, whether data was taken, or what kind of attack caused the outage. There is no follow-up filing in the log, so the eventual financial effect is not recorded here.
